我已经制作了一个自定义的UILabel类,我在框架的底部画了一条红线.
红线显示但我无法显示文本.

self.backgroundColor = [UIColor whiteColor];
LetterLabel *label = [[LetterLabel alloc] initWithFrame:CGRectMake(0,20,30)];
label.backgroundColor = [UIColor cyanColor];
label.textAlignment = UITextAlignmentCenter;
label.textColor = [UIColor blackColor];
[label setText:@"t"];
[self addSubview:label];
}
return self;
}
- (void)drawRect:(CGRect)rect {
// Drawing code
}
- (void)dealloc {
[gameWord release];
[super dealloc];
}
@end
解决方法
当然你的LetterLabel需要调用UILabel的drawRect：在某些时候？
-(void)drawRect:(CGRect)rect {
// Your stuff goes here
[super drawRect: rect];
}
